If we do not stop to help each other, what do we become? #internet

You know who did help me? Random strangers on Stack Overflow. People who had nothing to gain from helping me other than just trying to help someone in need.

At the time, I needed to know somebody cared enough to help me.

New Satellite Engine Could Use Earth’s Atmosphere as Fuel To Stay in Orbit Indefinitely #space #engineering

Choosing an orbit for a satellite involves balancing benefits and drawbacks. Very Low Earth Orbit (VLEO), which spans roughly 100 to 450 km (62 to 280 miles) above Earth, offers several advantages. Remote sensing cameras can capture sharper images, communications and radar systems need less power, and atmospheric drag helps remove inactive satellites from orbit naturally.

That same atmosphere also creates a major challenge. Even at these altitudes, air resistance slows spacecraft down, so satellites must produce thrust almost continuously to remain in orbit. Conventional propulsion systems require onboard fuel, often costly gases such as xenon.

As part of his PhD research at the University of Stuttgart, published on arXiv, Francesco Romano explored a different approach. His concept uses the atmospheric molecules responsible for drag as fuel for a plasma engine, potentially allowing satellites to remain in VLEO indefinitely without carrying a conventional supply of propellant.
